Is it possible to have an alias for the column value coming out of this pl/sql table ? It would be useful to perform joins etc.,
Rgds,

Try
SELECT column_value AS [alias goes here] FROM TABLE(...Urs

Column alias for spatial column within cursor loop using dynamic SQL
The following PL/SQL is trying to generate an error report for records or objects which are 3 dimensional or above.

Using column alias for calculations in same select list
Hi All,
I want to use a calculated column of query to create further calculated columns in same query using column alias. I have to do so because the calculation is too big to write it everytime.
e.g.
Select decode(Month, 1, Tran_January, 2, Tran_February, ....) as MonthTran,
Month, Year,
round(MonthTran/Intrest_rate, 2) as Amount <---(using previous alias)
from ledger;
Thanks in advance,
MonaProbably the easiest way of doing this is to write an inline view, viz
SELECT l.Month
, l.Year
, round(mt.MonthTran/l.Intrest_rate, 2) AS Amount
FROM ledger l
, (SELECT x.pk_col, decode(Month, 1, Tran_January, 2, Tran_February, ....) AS MonthTran
FROM ledger x) mt
WHERE l.pk_colunm = mt.pk_colunm
; If you have any criteria in a WHERE clause on ledger you shouldn't need to repeat them providing LEDGER does have a primary key column. You may need to tweak it a bit for performance, if LEDGER is a big table.

Hi,
I have to display the project_value as Project Value in graph series in oracle reports 10g.
my column name is project_value it is exactly shown in report but i want to show as Project Value. If i give like "Project Value"(giving in sql*plus) its not accepting so in graph its shows with "_" as in block value.I seem to remember that when you build the graph in Reports10g you can specify the column name in the graph. Havnt got the Report Builder with me at the mo so cant tell you more.

Thanks for answer to my first question. Now I have another problem.
Is there any way to print a report based on virtual table, which is created during some Pl/SQL procedure and can't be easily decribed by Select statementSELECT FROM PL/SQL TABLE IN ORACLE REPORTS 6I
The requirement is to populate a table and then select from that table in a report. The typical solution is to
populate a database table, but for situations where that is undesirable there is a way to select from a PL/SQL
table.
For example - for each employee we want to populate a PL/SQL table and then select from that table.
I used the following records in the emp table:
INSERT INTO Emp VALUES(123,'Bob','Sales',555,'28-JAN-79',35000,12,30);
INSERT INTO Emp VALUES(321,'Sue','Finance',555,'12-MAY-83',42000,12,10);
INSERT INTO Emp VALUES(234,'Mary','Account',555,'14-AUG-82',33000,12,20);
INSERT INTO Emp VALUES(623,'Joe','Sales',555,'28-JAN-79',35000,12,30);
INSERT INTO Emp VALUES(621,'Jim','Finance',555,'12-MAY-83',42000,12,10);
INSERT INTO Emp VALUES(634,'Jane','Account',555,'14-AUG-82',33000,12,20);
INSERT INTO Emp VALUES(723,'Fred','Sales',555,'28-JAN-79',35000,12,30);
INSERT INTO Emp VALUES(721,'Meg','Finance',555,'12-MAY-83',42000,12,10);
INSERT INTO Emp VALUES(734,'Jill','Account',555,'14-AUG-82',33000,12,20);
=============================================================================================
Step 1: Create a package spec in the report:
PACKAGE pkg_table IS
TYPE t_rec IS RECORD (
field1 NUMBER(6),
field2 VARCHAR2(30));
TYPE t_tab IS TABLE OF t_rec INDEX BY BINARY_INTEGER;
gv_tab t_tab;
FUNCTION populate (
p_empno NUMBER) RETURN NUMBER;
END;
Step 2: Create the package body:
PACKAGE BODY pkg_table IS
FUNCTION populate (
p_empno NUMBER) RETURN NUMBER IS
BEGIN
gv_tab.DELETE;
-- populate table as required - for demo purposes put in anything
FOR lv_ind IN 1..MOD(p_empno,20) LOOP
gv_tab(lv_ind).field1 := lv_ind;
gv_tab(lv_ind).field2 := 'row '||TO_CHAR(lv_ind)||' for emp '||TO_CHAR(p_empno);
END LOOP;
RETURN gv_tab.COUNT;
END populate;
END;
Step 3: Create the master query:
SELECT empno,
ename
FROM emp
Step 4: Add a formula column CF_populate to the master query that does:
function CF_populateFormula return Number is
-- for each emp fetched this formula will repopulate the PL/SQL table
-- and return the number of records in the table
begin
return pkg_table.populate(:empno);
end;
Step 5: Create the detail query:
-- we need to join this to the master and then ensure that for each
-- empno there are as many records fetched as there will be
-- records in the PL/SQL table
SELECT e1.empno,rownum
FROM emp e1, emp e2, emp e3
WHERE rownum <= :CF_populate
Step 6: Add formula columns to the detail query for each of the fields in the
PL/SQL table we want to display:
CF_Field1:
function CF_field1Formula return Number is
begin
return pkg_table.gv_tab(:rownum).field1;
end;
CF_Field2:
function CF_field2Formula return Varchar2 is
begin
return pkg_table.gv_tab(:rownum).field2;
end;
Step 7: Create the repeating frame and layout items to display the formula columns.
=============================================================================================
The same technique can be used to populate a master query. In a report level formula column
CF_Populate populate the PL/SQL table as required. In the master query we just need the rownum:
SELECT rownum
FROM emp, emp, emp
WHERE rownum <= :CF_Populate
Add the formula columns to display Field1 and Field2.

Problem with column alias: Unknown column 'avg_rating' in 'where clause'
Hello,
I have a basic sql statement as follows:

FROM
establishment e,
rating r,

where
etc...
and avg_rating >= 1
and 0=0
group by e.establishment_id
order by e.establishment_idI have used a column alias for "avg(r.rating)" and named it "avg_rating".
It works in my Mysql Query browser without problem but when I run it from Java I get this:

How to integrate DRM with third party tool for loading metadata in SQL table
Experts,
I am new to DRM and I have a requirement in which we want to integrate DRM with third party tool(lets say SQL table) as target and load metadata from DRM (Parent node, name , alias etc) to SQL table (same column name)
Is there any way we can integrate DRM to export the same to table directly instead to files. If yes what are the steps we have to follow.
Is there anyway we can customize DRM to execute queries or run batch
Can I have a basic example please.
Thanks in advance,
Regards,1. Use DRM Export to Table option, for that create an External Connection first for the Target Database and select the respective Tables to which you wish to Export the Hierarchy information.
2. You can perform most of the DRM Actions via the DRM_BATCH_CLIENT.exe.
Please refer to Using the Data Relationship Management Batch Client of DRM User guide.
let me know if you have any issues. -
Can we implement the custom sql query in CR for joining the two tables
Hi All,
Is there anyway to implement the custom sql query in CR for joining the two tables?
My requirement here is I need to write sql logics for joining the two tables...
Thanks,
GanaIn the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
Log on to your data source if necessary.
Under your data source, double-click the Add Command node.
In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
For example:
SELECT
Customer.`Customer ID`,
Customer.`Customer Name`,
Customer.`Last Year's Sales`,
Customer.`Region`,
Customer.`Country`,
Orders.`Order Amount`,
Orders.`Customer ID`,
Orders.`Order Date`
FROM
Customer Customer INNER JOIN Orders Orders ON
Customer.`Customer ID` = Orders.`Customer ID`
WHERE
(Customer.`Country` = 'USA' OR
Customer.`Country` = 'Canada') AND
Customer.`Last Year's Sales` < 10000.
ORDER BY
Customer.`Country` ASC,
Customer.`Region` ASC
Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
For more information about creating parameters, see To create a parameter for a command object.
Click OK.

Finding source database table/column name for a column in a view
Hi i need to be able to identify the original database table/column name for a column in a view.
e.g. say i have a view like this
create v1 as select a.name fname, b.name bname, c.name cname,......
from u1.names a, u2.names b. u3.names c
where .....
Now I want to find out that the database table/column name for the fname, bname and cname columns in the view v1, which in this instance is u1.name.name, u2.names.name, u3.names.name.
But i need to be able to do it for any view. Short of parsing the SQL is there an easy way of doing this?
Now obviusly I can't do this for virtual columns but I will know my column is not virtual as it has an index on it.But i need to be able to do it for any view. Short of
parsing the SQL is there an easy way of doing this?No, parsing the SQL is the only way. Good luck it is not something I would want to attempt. -
Selecting rows as columns in sql table
i have sql table like
currcode currdesc mth yr rate
SGD SINGAPORE DOLLAR 01 2013 .02
SGD SINGAPORE DOLLAR 09 2013 .02 (suppose have rates only for jan and sept )
RMB CHINESE RENMINBI 01 2013 .206
RMB CHINESE RENMINBI 02 2013 .207
For each currency rates for 12 months for every year
i want to show like (user will select the year)
currcode currdesc Jan Feb Mar Apr May Jun Jul Aug
Sept oct nov Dec
SGD SINGAPORE DOLLAR .02
.02
RMB CHINESE RENMINBI .206 .207
h2007you can use either of the below
1. Using PIVOT operator
SELECT currcode,
currdesc,
Yr,
[01] AS Jan,
[02] AS Feb,
[03] AS Mar,
[11] AS Nov,
[12] AS Dec
FROM Table t
PIVOT (MAX(rate) FOR mth IN ([01],[02],[03],[04],..,[11],[12]))p
2. using classical cross tab logic
SELECT currcode,
currdesc,
yr,
MAX(CASE WHEN mth = '01' THEN rate END) AS Jan,
MAX(CASE WHEN mth = '02' THEN rate END) AS Feb,
MAX(CASE WHEN mth = '03' THEN rate END) AS Mar,
MAX(CASE WHEN mth = '11' THEN rate END) AS Nov,
MAX(CASE WHEN mth = '12' THEN rate END) AS Dec
FROM table
GROUP BY currcode,currdesc,yr

Thank u for helping. Your 2nd solution working great. But using Pivot table giving me 2 rows,
RMB CHINESE RENMINBI
2013 NULL
NULL NULL
0.206 NULL NULL
RMB CHINESE RENMINBI
2013 NULL
NULL NULL
NULL NULL
0.207
h2007
Do you've any additional columns you've not shown in the post above?
to change NULLs to 0 use this
SELECT currcode,
currdesc,
yr,
MAX(CASE WHEN mth = '01' THEN rate ELSE 0.00 END) AS Jan,
MAX(CASE WHEN mth = '02' THEN rate ELSE 0.00 END) AS Feb,
MAX(CASE WHEN mth = '03' THEN rate ELSE 0.00 END) AS Mar,
MAX(CASE WHEN mth = '11' THEN rate ELSE 0.00 END) AS Nov,
MAX(CASE WHEN mth = '12' THEN rate ELSE 0.00 END) AS Dec
FROM table
GROUP BY currcode,currdesc,yr

VB code for executing pl/sql procedure, and displaying TABLE OUT parameter
Does anybody have any sample VB code (using OO4O) for executing a PL/SQL stored procedure, and then displaying (in Excel preferably) the following OUT parameters from the procedure:
(1) variable(s) of TYPE PL/SQL RECORD
(2) variable of TYPE PL/SQL TABLE defined as TABLE%ROWTYPE
(3) n variables of TYPE PL/SQL TABLE'S defined as table.column%TYPE;
Thanks.Here is what we use to bring in arrays of data from plsql. Here will be some sample vba code and plsql.
What the plsql need to run in an array of input dates and an array of ids to lookup for the dates (also needs the number of values in the arrray.
vba code...
Sub Bull()
Dim oDoc As Object
Dim oTable As Object
Dim oCell As Object
Dim ArrCtr As Integer
Dim iCount As Integer 'Counter
Dim DataDynaset As Object 'Dynaset for retrieved values

Dim TWDataDynaset As Object 'Dynaset for retrieved values
Dim PDDataDynaset As Object 'Dynaset for previous day retrieved values
Dim MSTssCodes As Variant ' TS Codes Array
Dim NumRows As Integer 'Number of rows in the table
Dim NumColumns As Integer 'Number of columns in the table
Dim NumArrayVals As Integer 'Number of array values (actual number - 1)
OraLogin
NumRows = 83
NumColumns = 11
'One less than number because we start at 0
'NumArrayVals = 5
NumArrayVals = 117
ReDim DateArr(NumArrayVals)
MSTssCodes = Array(3398, 3406, 3391, 3385, 3413, 3378, _

4974, 2803, 4735, 4719, 2837)
****** NOW THIS WILL GET READY TO SEND TO PLSQLGetData MSTssCodes, DateArr, DataDynaset, NumArrayVals + 1
.... more suff in the sub
Sub GetData(Tssids, DateArray, TmpDataDynaset, NumRetVals)

'Fill the arrays
For I = 0 To NumRetVals - 1

Cannot access columns in a result set using table alias in Oracle database
I have a query which joins a few tables. There are a few columns in various tables with identical names. In the query, I have assigned table aliases for each table thinking it'll be the manner in which I access a specific column in a specific database table. However, when trying to retrieve the column, I'm getting an exception stating "Invalid column name". I had no problem doing so in my last project when I was coding against MySQL database so this is likely to be a driver implementation issue. My current workaround is to assign a column alias though I find this to be annoying and it does make the query very verbose.
My question is whether this option is perhaps a configuration issue, a bug, or something that I'm missing. Also, I would like to know if anybody has an elegant workaround without accessing columns using their numeric index.
I'm querying an Oracle 10i database in a managed environment (database connection is obtained from a Weblogic data source).
Sample query:
select
a.address1,
d.address1
from
account a
inner join
department d on a.department_id = d.department_id
where
a.account_id = 1000;
When trying to access a ResultSet instance in the following manner, I will get an exception:
rs.getString("d.address1");
Retrieving "address1" will return the first column in the select clause.jonathan3 wrote:

You can try extracting the meta data to see if it has a name without the alias. Probably not.
Also, I would like to know if anybody has an elegant workaround without accessing columns using their numeric index.One can only suppose that you consider using names "elegant".
